Description

The Unicode character U+2124, known as the DOUBLE-STRUCK CAPITAL Z, is a typographical symbol that represents an uppercase letter 'Z' in a double-struck or bold style. In digital text, this character is often used to denote mathematical expressions or variables, as well as to emphasize certain elements within a document. Its double-struck appearance makes it easily distinguishable from regular capital letters and can help improve the clarity of mathematical or technical documents. The DOUBLE-STRUCK CAPITAL Z has no specific cultural or linguistic significance but is widely used across various industries, such as mathematics, engineering, and computer science, to convey important information in a visually distinct manner.

How to type the symbol on Windows

Hold Alt and type 8484 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+2124. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+2124 to binary: 00100001 00100100. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
    11100010 10000100 10100100
